already mentioned monica under drop rate boosters. xiao is not reliable enough to be used compared to other archers.
also, I actually listed the golds on previous page as I remembered, not exactly bernice getting any priority. but it's true that she fulfills her role as a gold for her class very well, which made her easily memorable to me to be mentioned early.
but for the 'middle man' list, they're largely split outright into usable and not usable. anything I didn't list on 1st page is almost = useless. (note the almost. too lazy to start another bullshit argument for half-decent units)
